Who has never uttered the words: "I lack self-confidence"? Martine feels comfortable in her relationship but panics at the idea of failure, so she avoids any professional project that is somewhat ambitious. With Capucine, the opposite happens: a successful woman in her profession, she avoids close relationships, convinced that she cannot be loved. Charles speaks easily in front of an audience, while Kevin is paralyzed. Thibault, on the other hand, succeeds in everything he undertakes. Nevertheless, they all admit that they lack self-confidence…

Inability to choose or express oneself, fear of rejection or ignorance, fear of the future or others, doubts about our knowledge or popularity—what exactly is self-confidence? Isabelle Filliozat dispels some accepted ideas and guides us towards a better understanding of our reactions. With her usual clarity, she also suggests exercises to feel comfortable with ourselves and others and to penetrate the secrets of those whose self-confidence we envy. You, who lack inner certainty or confidence in your abilities, will learn to love yourself a little more every day.
